47.Have a IDE drive ? Improve disk performance by changing to DMA access mode

If You are an average user, there is a good chance that your are using a IDE hard disk that supports DMA access. Even Windows XP fails to set the DMA mode correctly for the IDE device designated as the slaves on the primary IDE and secondary IDE channels. Most CD-ROMS are capable of supporting DMA mode, but the default in XP is still PIO. Setting it to DMA won't make your CD-ROM faster, but it will consume less CPU cycles. Follow instructions below:1. Open the Device Manager and navigate to "IDE ATA/ATAPI Controllers", expand it and double-click on "Primary IDE Channel"2. Under the "Advanced Settings" tab, verify the "Device 1" setting. If transfer mode is set to PIO Then set it to "DMA if available". Repeat the step for the "Secondary IDE Channel" if You have devices attached to it. Reboot the sytem.
